LOOM FOR \NEAVING DOUBLE-RULE. FABRICS.

SPECIFICATION forming part of Letters Patent No. 311,961, dated February10, 1885.

Application filed November 7, 1882.

To aZZ whom it may concern:

Be it known that I, CHARLES COUPLAND, of Seymour, in the county of NewHaven and State of Connecticut, have invented certain Improvements inLooms for \Veaving Double Pile Fabrics, of which the following isaspecification.

This invention relates to looms that are more particularly designed forweaving double-pile fabrics, but which, by omitting the pile-warp andthe mechanism for actuating the warp, may be employed for simultaneouslyweaving two separate fabrics.

In the variety of looms to which my invention more particularly refers,there are employed an upper and lower race and fixed upper and lowershuttle-boxes placed in substantially the same horizontal planes as theraces aforesaid, and provided with means for simultaneously projectingthe shuttles upon said races from the shuttle-boxes. Such looms asheretofore constructed, however, have been incapable of weavingdouble-pile fabrics with their intermediate threads, and theirshuttleprojectin g mechanism has been comparatively unstable and liableto get out of order.

The object of my invention is to provide a loom of the class indicatedwhich will be suitable for weaving double pile fabrics that, whenseparated by cutting their intermediate pile-threads, will affordfabrics having a pile or velvet surface, and which will also be certainin its operation and not liable to get out of order during thevicissitudes of use.

My invention comprises certain novel combinations of parts, hereinafterfully particularized in the claims, whereby said objects are secured.

Figure 1 is a front view of the upper portion of the lay of theloo1n,with theinvention applied thereto. Fig. 2 is a View of one end ofthe said lay. Fig. 3 is a transverse sec tional view taken in the line00 x of Figs. 1, 2, and 4t. Fig. 4 is a plan view of the end shown inFig. 2, and Fig. 5 is a perspective detailed View. 7

At each end of the lay is a pair of shuttleboxes, A and 13, each beingdesigned for the reception of a separate shuttle, and the one, B, beingplaced over the other, A. The shut- (Xo model.)

G is the top rail of the lay, and D is the I reed.

Extending down from the top rail, G, are a series of prongs or fingersE, the lower ends of which are bent inward or backward, as representedin Fig. 5, thereby forming a skeleton race in substantially the samehorizontal plane as the bottoms of the boxes B. The prongs or fingers Eare placed at such distance apart that their-lower parts, 6, willsupport the shuttle in passing over the same. The object of thisskeleton race is to provide a means for supporting the uppershuttleduring the move- -ments which are imparted to it in forming the upperweb of the fabric without permitting the upper shuttle itself to run incontact with the warp. The lower-parts, e, of the skeleton race,constituted by the prongs or fingers E, are so arranged that the lowerwarp may rise between them in the operation of weaving, and are taperedin such manner that the warps may readily pass between them withoutcatching, and a space should be afforded between their rear extremitiesand the reed in order to allow. the filling to draw down for the purposeof being beat up, all as will be read ly understood by those familiarwit-h the practical construction and operation of looms.

In'order that the two shuttles Aand Bmay be simultaneously projectedover the races respectively formed by lay-beam a and fingers E, asindicated in Fig. 1, the horizontal partition f, which constitutes thebottom of the upper shuttle-box, and also the top of the lowershuttle-box on each end of the lay, is longitudinally slotted, asrepresented in Fig. 3, and at g in Fig. 4, and a peculiarly-constructeddouble picker, F, is arranged. to move through both of the said boxes.The upper part, on. of said picker traverses the upper shuttle-box,while the lower part,n,of said picker traverses the lower shuttle-box,the said upper and lower parts, m and n, of said picker F beingconnected by a neck, '1", as represented in said Fig. 3. Provision ismade for the insertion of this double picker in place by means of anopening, 8, at the rear end of the partition f, the said openingextending the entire width of the interior of the shuttle-boxes, andbeing of a length, measured in adirection longitudinally of theshuttle-boxes, slightly exceeding the thickness of the picker F, so thatthe latter may be readily dropped into place and into positionforlongitudinal movement within the shuttle-boxes.

A single picker-staff of the ordinary or any usual construction isarranged in substantially the samelrelation with the picker F as thecommon picker-staff is arrangedwith regard to a single picker of anordinary single shuttlebox, so that the single picker-staff, actingthrough thedouble picker F, give simultaneous motion to the two shuttlesas the same are projected from the two shuttle-boxes B and A, the twoshuttles being thrown together and in unison alternately from the onepairof shuttle-boxes to the other.

In order to properlyguide, steady, and sup- 7 port the picker during itsmovement, there is provided a fixed horizontal guiding-rod, a whichpasses through a slot or opening of corresponding sizeand shape formedin the upper end of the picker, as more clearly indicated in Fig. 3.

Except for the purposes of the combinations hereinafter set forth in theclaims, I do not in the Letters Patent to be issued on this applicationclaim the herein-described skeleton race, inasmuch as the said skeletonrace constitutes an elementin combinations claimed in certain otherapplications for Letters Patent filed by meas, for example, in myapplication filed November 7, A. D. 1882, and designated by the SerialNo. 76,152. Further, I do not in the Letters Patent to be issued onthis, my present application, claim with a double picker constructed andar-.

ranged to simultaneously actuate the shuttles of both boxes, the oneshuttle upon and over the lay-beam, the other upon and over the skeletonrace, all substantially as and for the purpose herein set forth.

2. The combination of a lay having fixed double shuttle-boxes placedparallel and one above the other, the slotted partition f between saidboxes. and the skeleton race placed above and parallel with the lay,with the double picker composed of theparts m n and neck 1", andarranged to be operated by a single picker-staff, the wholeconstructedand arranged substantially as and for the purpose herein set forth.

3. The combination of a lay having fixed double shuttle-boxes placedparallel and one above the other, the slotted partition f be tween saidboxes, and the skeleton race placed above. and parallel with the lay,with the double picker composed of the parts at n and neck r,-and theguide or rod (1*, provided to steady said double picker, the wholeconstructedand arranged substantially as and for the purpose herein setforth.
